“According to the data, Google received 982 geofence warrants in 2018, 8,396 in 2019 and 11,554 in 2020.”
A geofence warrant asks Google for everyone who was near a place at a time. That is a dragnet, not a search of a suspect. Requests grew twelvefold in two years, almost all from local and state police. Google only gets them because it keeps the location history in the first place.
